I’d have a lengthy conversation with the animal.
I’d have a million questions, but first, if the animal spoke God’s truth to me, I’d listen, because I’d know that this unnatural thing happening could only be from God, if the animal is speaking God’s Truth.
After that, it’d be questions like: “so...when I talk to my dog, what doese she actually hear?”
...and...
“What do the birds and the bees think when they hear humans talking about the birds and the bees?”
Maybe we’ll get to find out when we are in heaven.
